Fixed most of the unit tests in ChartUnitTest by using new test data files (with some refactoring). The testSetGraphDataSeries test is currently failing/ignored and still needs to be fixed.
Replaced tabs by spaces.
Small textual changes.
Removed unused fields.
Split the constructor by creating createBarRenderer.
Simply always return maxIntensity from getMaxTicIntensity, because the field is initialized to zero.
Small changes: put static fields at the top, made variables and parameters final if possible, changed fields into variables if possible, removed unnecessary null field initializations.
